Anabolic steroids can cause many adverse effects . Most of these side effects are dose dependent, the most common being elevated blood pressure , especially in those with hypertension ,  and harmful cholesterol levels: some steroids cause an increase in bad cholesterol and a decrease in good cholesterol .  Anabolic steroids such as testosterone also increase the risk of cardiovascular disease ,  or coronary artery disease   in men with high risk of bad cholesterol . Acne is fairly common among anabolic steroid users, mostly due to increases in testosterone stimulating the sebaceous glands .   Conversion of testosterone to dihydrotestosterone (DHT) can accelerate the rate of premature baldness for those who are genetically predisposed.
Each user experiences their own unique feelings when using steroids and coming off the drug. When someone chooses to stop using they can experience a variety of withdrawal symptoms linked to addiction. Symptoms can include mood swings, fatigue, restlessness, loss of appetite, insomnia, reduced sex drive, the desire to take more steroids, and depression. Evidence for steroid addiction is certainly not as strong as it is for other drugs like cocaine or heroin. Though it is clear that people develop a tolerance and dependence on them and willingly experience negative consequences when using steroids - both of which are signs for drug dependence.
